中文摘要：

本文从L—J维里状态方程、L—J径向状态方程、TIP4P维里状态方程以及TIP4P径向状态方程四种模型出发，利用分子动力学模拟技术，进行了湿空气性质的研究。对不同状态方程的模拟结果的稳定性进行了探讨，发现径向状态方程的稳定性要好于维里状态方程。最后采用径向分布方程及TIP4P模型，模拟了湿空气的性质。结果表明湿空气在低温、高压和高含湿量下，其性质不再接近于理想气体的性质。

英文摘要：

The properties of moist air were simulated by using Lennard-Jones virial state equation, Lennard-Jones Radial Distribution Function （RDF） state equation, TIP4P virial state equation and TIP4P RDF state equation according to molecular dynamic simulation. The stability of simulated results of different states equations was discussed. It is found the RDF state equation has better stability than one of virial state equation. At last the properties of moist air were simulated by using RDF state equation and TIP4P model. It is shown that properties of moist air do not satisfied one of ideal gas under the condition of low temperature, high pressure and humidity ratios.
